Definitions

  • the invention relates to a dispenser for portioned dispensing, in particular of pasty masses, with a piston which moves in the dispenser storage space in accordance with the actuation steps in the direction of the mouthpiece and a slide which can be displaced from an actuation handle in the direction of the mouthpiece and which is guided to the dispenser housing by a lip in a sealed manner and has a wing which lies sealingly against the wall of an ejection channel during the actuation stroke and stands out from the wall of the ejection channel during the return stroke.
  • a donor of this type is known from DE-OS 29 16 206.
  • the slide is guided in an ejection channel arranged transversely to the storage space.
  • the storage space and the discharge duct are in flow communication via a passage.
  • the slide dispensing the portioned quantity has a wing in the form of a ring sleeve on the mouthpiece side. This is inclined so that there is a ring funnel widening in the dispensing direction.
  • the plunger of the storage space which migrates in the direction of the mouthpiece in accordance with the actuation steps.
  • the slider is also through one beyond the through leave lying lip sealed.
  • the latter runs on the wall of the discharge channel and, like the sleeve forming the wing, is designed in a ring shape.
  • the slide After the portion quantity has been dispensed, the slide returns to its basic position under spring load.
  • the wing overflows the mass lying behind it, leaving its sealingly guided contact on the corresponding wall of the ejection channel, that is, angling it radially somewhat. After reaching the basic position, the sash is locked again.
  • the design is not only too expensive for a mass-produced item; it also requires exaggerated precision for a mass-produced article.
  • the stability of the wing is to be matched to the force of the valve spring. If this is designed too hard, for example, the stability of the sleeve collapses. There are output problems. If, on the other hand, the stability of the sleeve is chosen to be higher, the mass to be retightened will no longer overflow. The function depends too much on the degree of viscosity of the mass. In terms of construction, the transverse position of the discharge duct to the storage space is also disadvantageous insofar as there are injection molding problems there. Finally, the number of parts is too high.
  • the object of the invention is to design a generic dispenser in a technically simpler, more advantageous manner in such a way that on the one hand a special mouth-side valve can be dispensed with, but the level column remains uninterrupted until the last portion is dispensed, all with a considerably reduced number of parts such donor.
  • a structurally advantageous embodiment with respect to the slider is that it and the actuating button are made of the same material, that is, they are made in one piece.
  • the actuation surface of the key extends essentially transversely to the discharge path of the filling material.
  • the ejection channel is advantageously coaxial with the mouthpiece. Furthermore, the construction has proceeded in such a way that transverse webs extending from wall to wall of the retraction form a contact surface for the curved return spring of the actuation button. The return spring is supported on the end faces of these webs. It is therefore supported in a sliding manner. If a sliding movement in this regard is to be dispensed with, an inexpensive solution offers itself in such a way that the return spring that bulges in the direction of the ejection channel extends from the outer end of the double-arm actuation button below and is supported with its free end in the lower inner corner of the ejection channel on the side of the retraction. Taking into account the tilting movement, the spring bulges out in the direction of the kink between the slide and the actuation button in a way that is favorable for stress.
  • the dispenser of both exemplary embodiments has a cylindrical storage housing 1. Its storage space 2 is closed at the bottom by a piston 3, which moves in the direction of the ceiling 4 of the storage housing 1 in accordance with the actuation steps. To assign the piston 3, the storage housing 1 is open at the bottom. A funnel-shaped exposition of the lower housing edge 1 'facilitates the assignment of the piston after the filling.
  • the piston is pot-shaped.
  • the pot rim and bottom zone each form an annular sealing lip 5.
  • the ceiling-side serves as a scraper lip and the edge of the housing as a support lip and has a greater clamping force.
  • the ceiling 4 carries a mouthpiece 6. This is off-center. It starts out as a tube with a rectangular cross-section from a chamber section 7 which also projects beyond the ceiling 4 and is segment-shaped in cross-section. The latter has approximately four times the cross section of the mouthpiece 6.
  • An ejection channel 8 adjoins the chamber section 7, viewed in the direction of the storage space 2. This is coaxial with the mouthpiece.
  • the inside dimension of the discharge channel 8 is larger in cross section than that of the mouthpiece 6 and slightly larger than that of the chamber section 7.
  • the discharge channel 8 receives a vertically displaceable slide Sch.
  • the latter is V-shaped. Its shorter V-leg a is designed as a wing 9.
  • This lies sealingly against the wall 11 in the sense of the portioned dispensing of the filling content, here a pasty mass 10.
  • a so-called film hinge 12 via which the flat-shaped wing 9 is connected to the linearly moved, longer V-leg b.
  • This is supported on the outer surface of a wall 13, which forms the ejection channel 8 and lies parallel to the vertical wall 11, of a recess 14 starting from the ceiling 4.
  • the latter continues on the discharge channel side into the shaft and also laterally delimiting, vertical, also parallel narrow walls 15, which are rooted in the wall of the storage housing 1.
  • the length x of the wing 9 is - seen in the folding plane - greater than the width dimension y of the discharge channel 8 lying in this direction.
  • the dimensional coordination is such that an acute angle alpha of 45 ° between the V-legs a and b is present.
  • the V-tip lies in the area of the wall 13.
  • the narrow edge 16 (end face) of the wing 9 is chamfered so that there is a larger contact area with the wall 11 than the thickness of the wing. Rounded according to the cylindrical shape of the wall of the storage housing 1 and the wall of the integrated discharge channel 8, which wall takes a corresponding partial shape.
  • the one sealing lip L is located on the wall 13 of the recess 14. It is realized there across the entire channel width as a strip which is triangular in cross section to the direction of displacement, one side of the triangle being seated on the wall 13 as a base.
  • the other guide sealing lip L for the slider Sch is located on the discharge channel-side surface of the V-leg b, also extending over the entire width of the discharge channel 8. It is seated on a freely resilient flap 17, which projects above the ceiling 4 towards the bottom. The latter adjoins an inside wall 18 of the chamber section 7.
  • the lip L tapers out like a blade and also extends at an acute angle, essentially parallel to the wing 9, but at a distance from it in the direction of the mouthpiece which enables the required actuation stroke. Seen spatially, this fixedly arranged guide seal lip L, starting from the vertical tab 17, runs from top left to bottom right. The wing 9 extends from the bottom right to the top left.
  • the guide sealing lips L which are also formed as triangular strips in cross section, also sit with their one broad side as the base, so that the triangular tips point transversely to the slide movement plane.
  • the guide sealing lips L lie in such a way that one leads to the wall 13 of the recess 14, while the other, on the other side of the V-leg b, the guide sealing lip L leads to the lower-drawn section of the discharge channel-side wall 18. Both walls run parallel to each other and thus form a guide shaft.
  • the only linearly moved V-leg b of the slide sealingly passes through a slightly enlarged gap 19 of the ceiling 4.
  • the gap dimension and that of the guide shaft adjoining at the bottom is selected such that a width remains between the wall 13 on the intake side and the wall 18 on the discharge duct side such that the slide can be inserted there with the wing 9 folded, the latter after leaving the lower-lying guide sealing lip L. due to its restoring force, it can be moved into the position shown in the figures in such a way that it can move with elasticity.
  • the V-leg b of the slider Sch merges into an actuation button 20 according to both exemplary embodiments.
  • This is designed as a double-armed lever. It is a part of the slide Sch stiffened by a shell-like edge wall 21. From its edge wall 21 there are diametrically opposed stub axles 22, which are clipped into bearings 23 of an annular wall 24 of the storage housing 1 projecting above the ceiling.
  • the actuating button 20 which is formed in one piece with the slide, assumes the position shown in FIGS. 4 and 5 in the demolding position.
  • the V-leg b extends vertically and the part forming the actuating button 20 is angled essentially transversely thereto, in an increasing orientation at the transition point between the chamber section 7 and the mouthpiece 6.
  • the breakthrough zone is cut out as a tongue so that it projects approximately vertically from the actuating surface. It therefore runs approximately parallel to the edge wall 21 of the actuation button 20. In this respect, it functions as a skirt covering the lower region of the actuation button 20.
  • a curved return spring 26 extends from the underside thereof. This is formed at the same time and acts in such a way that the slide assumes the readiness to dispense position shown in FIG. 1.
  • the return spring is supported on the end edges 27 'of webs 27 on the drawing-in side. The latter are in the tilting plane of the actuation button. They are aligned in parallel and extend from the wall 13 of the retraction forming the support of the slide to the opposite wall 13 'thereof. As can be seen in FIG. 1, the upper end edges 27 ′ of the webs 27 run obliquely in the direction of the discharge channel 8.
  • the stroke limitation is achieved by means of a stop on the actuating button side, in that the top edge 21 'of the longest section of the edge wall 21 strikes the top 4' of the ceiling 4 lying beyond the return spring.
  • the corresponding position results from FIG. 2.
  • the wing has not yet stepped against the step formed on a cross-sectional reduction between the discharge channel 8 and the chamber section 7. 2, the return spring 26 has clearly moved from the substantially parallel position to the longest section 21 'of the edge wall 21 into a clear spreading position.
  • the restoring force causes the actuation button and thus the slide to be returned to the position shown in FIG. 1.
  • the longest section 21 ' is diametrically opposite to the narrow edge 16.
  • the return spring 26 is not arranged in a sliding allocation for retraction; rather, the return spring 26, which is slightly bulged in the direction of the discharge channel 8, starts from the outer end of the double-armed actuation button 20 in such a way that its free end 26 'is supported on the discharge channel-side, lower inner corner 14' of the recess 14. It essentially penetrates the confiscation diagonally.
  • the return spring 26 holds the actuating button 20 in a limiting system the upper end face 13 "of the wall 13.
  • the end of the double-armed actuation button 20 located near the film hinge 12 is supported there.
  • the immediate area adjoining the film hinge 12 on the slide side deforms slightly when the push button is actuated a deformation of this area is accepted.
  • the mass to be dispensed otherwise rests on the output-side surface of the wing 9 in such a way that the sealing contact with the wall 11 is not canceled.
  • This all-round sealing means that the piston 3 is pulled over the level column of the pasty mass 10, to which it practically "sticks".
  • the slide is re-immersed without any great stress on the pasty mass due to the acute-angled immersion thereof, the wing 9, tilting around the film hinge point 12, folding in the direction of the V-leg b.
  • the slider dips into the mass and scoops up the next portion.
  • the restoring force of the material causes the wing 9 to rest against the wall 11 again.
  • the next portion can be removed, etc.
  • the paste-like mass present in the nozzle-like mouthpiece tube acts as a stopper that seals off the outside air draws easily into the mouthpiece 6, even while avoiding a supernatant that may dry soon.
